This study examines how incorporating different electronic feedback devices (i.e., clickers versus web-based polling) may affect specific types of student engagement (i.e., behavioral, emotional, and cognitive engagement), whether students’ self-efficacy for learning and performance may differ between courses that have integrated clickers and those that use web-based polling, and whether using ...

Polling models are used as an analytical performance tool in several application areas. In these models, the focus often is on controlling the operation of the server as to optimize some performance measure. For several applications, controlling the server is not an issue as the server moves independently in the system. We present the analysis for such a polling model with a so-called autonomou...

• 40 polling centers were assigned to receive designed information, with 5 different interventions: individuals were shown the same debate as in other polling centers; individuals were shown a ‘getting to know you’ video of candidates; individuals listened to a radio recording of a journalist summarizing candidates policy positions; individuals participated in a ‘lab’ experiment where they were...

We study the expected delay in a cyclic polling model with mixtures of exhaustive and gated service in heavy traffic. We obtain closed-form expressions for the mean delay under standard heavy-traffic scalings, providing new insights into the behaviour of polling systems in heavy traffic. The results lead to excellent approximations of the expected waiting times in practical heavy-load scenarios...

E-polling systems are a fundamental component of any edemocracy system as they represent the most appropriate tool for fostering citizens participation to public debates. Contrarily to e-voting protocols, they are characterized by less stringent security requirements in particular they can tolerate errors affecting a small percentage of votes, without the compromision of the final result. Thus ...

This study explores the effects of integrated concept maps and classroom polling systems on students’ learning performance, attentional behavior, and brainwaves associated with attention. Twenty-nine students from an Educational Research Methodology course were recruited as participants. For data collection, inclass quizzes, attentional behavior analysis, and a 20-minute structured interview we...

-Four kinds of service types are defined in IEEE 802.16. In order to provide the Quality of Service (Qos) for different services, the system must use a reasonable resource allocation method and scheduling algorithm to efficiently and fairly allocate bandwidth resources. Although in the IEEE 802.16 MAC, for the uplink real-time polling service (rtPS) and non-real-time polling service (nrtPS) bus...

This paper derives the exact mean waiting time for an asymmetric polling system with general service order and mixed service discipline. The mixed service discipline means that the service discipline of each stage (a turn in the service order sequence) for the same station can be gated or exhaustive. The gene-l-al service order denotes that each station can be polled more than once in a polling...

We consider the cyclic polling system with two queues. One queue is served according to the exhaustive discipline, and the other queue is served according to the 1-limited discipline. At least one of the service and/or switchover times has a regularly varying tail. We obtain the tail behavior of the waiting time distributions. When one of the service and/or switchover times has an infinite seco...
